            <h3>各项优化技术的贡献</h3>
            <p>本次优化通过三种核心技术的组合实现了显著的性能提升：</p>
            
            <ul>
                <li><strong>并行测试执行引擎</strong>：通过同时执行多个测试用例，充分利用多核CPU资源，大幅缩短了总体测试时间。</li>
                <li><strong>智能等待机制</strong>：替代了传统的固定延迟等待，根据实际情况动态调整等待时间，减少了不必要的等待开销。</li>
                <li><strong>资源复用技术</strong>：通过资源池化管理，避免了重复创建和销毁测试资源，提高了资源利用效率。</li>
            </ul>
            
            <h3>最佳实践建议</h3>
            <ol>
                <li><strong>并行度选择</strong>：根据测试环境的CPU核心数和内存大小，选择合适的并行度。一般建议并行度不超过CPU核心数的2倍。</li>
                <li><strong>资源池配置</strong>：根据测试规模调整资源池大小，避免资源耗尽或过度分配。</li>
                <li><strong>智能等待参数</strong>：针对不同类型的操作，调整智能等待的超时时间和重试间隔，以达到最佳效果。</li>
                <li><strong>测试套件划分</strong>：合理划分测试套件，避免相互依赖的测试用例同时执行，减少资源竞争。</li>
